CARLTECH IT COMPLEX
4.9★★★★★75 Google reviews
CARLTECH IT COMPLEX operates as a computer retailer and repair shop out of Pritchard Street in Johannesburg's CBD, selling new and used computers, parts, and accessories, with listings running through the Bob Shop marketplace. It's worth being upfront about what this business is: a hardware-focused computer store and repair service, not a managed IT support provider handling networks or cybersecurity for a business. With 75 reviews, it carries the most volume of any provider in this search.
What people praise
- Reviewers describe safe, well-packaged delivery, including a cross-border order to Zimbabwe
- Praised for letting buyers test hardware, like SSD health and performance, before purchase
- Customers say pricing was fair with no pressure to upgrade or add extras
- Noted for patient, friendly guidance when choosing between laptop options
Worth knowing
- This is a hardware retailer and repair shop first, not a managed IT support provider, so it's the wrong fit if you need ongoing network or security management

4.9★★★★★59 Google reviews
Biostec Group, based in Braamfontein, sells refurbished laptops and handles device repairs, with reviews also mentioning cell phone sales and basic web work.

- Praised for quick turnaround on repairs, one reviewer got a laptop fixed and working perfectly
- Multiple customers describe the buying process as smooth with no surprises

4.9★★★★★20 Google reviews
Nomndayi Technologies, founded in 2020 and based near the Johannesburg CBD, offers desktop support, internet setup, data recovery, and web development for small businesses across the city.

What people praise
- Reviewers describe the service as one call away and efficient
- Praised for laptop screen and battery repairs done at a fair price
- One reviewer calls out reliability and flexibility specifically
- Multiple reviews span multiple years, suggesting repeat, ongoing trust

Claim this spot › How we scored these providers
We pulled five figures straight from Google for every business: the star rating, how many reviews back it up, a confidence score that weighs rating against volume so a perfect score on a handful of reviews doesn’t outrank a strong score on dozens, how recently reviews are still coming in, and how complete each listing is, website, phone, hours. No business can pay to change any of these numbers. The order below reflects that scoring alone.
What does IT support cost in Johannesburg?
Pricing depends heavily on the type of work: a one-off repair or hardware purchase is priced very differently from an ongoing managed IT retainer covering network monitoring, security, and support seats. Business-focused providers usually price around scope (number of devices, users, or sites) rather than a flat rate. We don’t have a verified, current local pricing source to publish exact figures here, so get a written, itemized quote from at least two providers before committing to either a repair or a retainer.
Covering Johannesburg’s CBD and beyond
Most of the providers on this list are based in or near Johannesburg’s central business district, around Pritchard, Rissik, and Von Brandis streets, with several also serving clients in Braamfontein and further afield, including nationwide support for remote work. If you’re searching for IT services near me in Johannesburg, confirm whether the provider offers on-site visits or remote-only support, since that split varies business to business.
What to ask before you hire an IT provider
- Do you offer one-off repairs, an ongoing retainer, or both?
- What’s your average response time for an urgent issue?
- Do you provide remote support, on-site visits, or both?
- What happens to my data if a repair or migration goes wrong?
- Can you provide references from a business similar in size to mine?
- Is cybersecurity or backup monitoring included, or billed separately?
Frequently asked questions
Are these rankings paid?
No. Rankings come from public Google data, ratings, review counts, and recency. A business can pay to be a Featured Partner, which gets a badge and top placement, but that never changes another business’s score or position.
How did you choose these five providers?
We compared IT and computer service providers serving Johannesburg on real Google ratings, review volume, and how recently customers were still reviewing them, then checked what each actually offers using their site and customer reviews.
How often is this page updated?
We last verified this data in July 2026. Ratings and review counts shift over time, so treat the numbers as a snapshot, not a permanent ranking.
What’s the difference between a computer repair shop and a managed IT provider?
A repair shop fixes or sells individual devices as one-off jobs. A managed IT provider takes ongoing responsibility for a business’s network, security, and support, usually under a monthly retainer. Two providers on this list, CARLTECH and Biostec, are primarily the former.
Should I choose a local Johannesburg provider over a national one?
A local provider is often faster for on-site visits and hardware drop-offs. If your needs are mostly remote, like cloud or Microsoft 365 support, a provider’s physical location matters less.
The bottom line
For a business that wants ongoing IT management, Solid Systems is the safest default, nearly two decades with the same client says more than any star rating. For hardware sales and repairs, CARLTECH IT COMPLEX has the strongest, most reviewed track record. Match the provider to the job before you call.
